You can not control the fan speed on a PA-500. Your show system environmentals output seems to be off, as it should show only one True/False for alarms. Yours is showing False then True. Try running this command to see what the RPMs are instead...
show system state | match fan
You may want to reboot the firewall and see if the results from the show system envrionmentals appear the same. If the issue persists you should open a case with support.
the false/true are actually 2 separate collums
rpms (is the fan spinning): true
The output is normal for a PA-500 as the fan speed is not dynamic, so the sensor only reports if the fan is spinning or not.
If one of the fans is making an unusual sound or is unusually loud, I would recommend contacting TAC as it could need to be replaced
